Seems to be a ceiling of around 320hp with bolt ons for 93 pump which isnt really that much above factory

So ruling out e85, which seems to be top on everyones list, due to no access to this fuel, what other mods would you recommend to get the most out of 93 pump?

 

320 WHEEL hp is a big jump from factory.

Full exhaust (including an O2 housing), intercooler piping, intercooler, intake, injectors and cams can get you good power with a 9 turbo. My car mad 350/350 with that setup on 91 octane. You'll get another 25hp or so with 93..

 

I would suggest this as the cheapest path to get to 320 hp. Injectors (maybe 800cc), Walbro 255 fuel pump, LICP, Full 3-inch TBE (02 housing included), and Air intake.

 

I made 325 with the stock evo 8 turbo,hks 280's,full catless exhaust,intake and a tune.

 

Cams, turbo back exhaust, bigger fuel pump, air intake, and upper/lower ic piping. I'm assuming you're also getting it tuned to maximize the HP of all the mods.

 

- fuel pump
- turbo back exhaust
- O2 housing
- Lower ic pipe
- drop in filter (K&N) or intake
- Tune
you should see 320+ on a dynojet around 25ish psi (depending on octane)

 

Then later down the road:
- Cams with springs upgrade
- Fuel injectors
- Intercooler
- headstuds
- turbo!!

 

LOL I don't like this question I like power made easy,cheap,hence e85 I love that stuff.Imo the best thing you can do on a stock turbo is e85 on less mods.If stock turbo is your limit and you want gains e85 is the answer.I look at it this way I don't like to buy parts more than once if I can help it . buying parts to max out a stock turbo isn't worth it semi small,injectors(under 1000cc,pump(stock no less than 255),o2 housing( high price for only stock turbo),cams(stage 1 or below 272).you can go more if you choose to go bigger turbo.seems a waste to mod heavy on only stock turbo that's all I'm saying.mod for the future lol.sounds like a slogan

 

Exhaust/DP/TestPipe (I consider this one mod), Bigger injectors, Fuel Pump, Cams (springs and retainers if needed) and Tune. 400ish on E85 all day.

 

Others have already made great suggestions for mods, so see what will work best for you and go for it.
As far as 320hp not being much over stock, that's not necessarily true, you have to find out what a stock evo/your evo dyno's at on that dyno to really get a good perspective on how much power your making.

 

(thumbs UP)

 

I would start with intake, intercooler piping, exhaust, downpipe, and go catless. Next step to really feel an increase in power (which will require a tune) would be bigger injectors 750cc-1000cc, Walbro 255 fuel pump, 272 cams, ported exhaust manifold, and bigger intercooler core. Your evo9 turbo should get you close to 400whp on 93 with all the following supporting mods with a good tune. You can always upgrade to an FP green or red if you wish

 

320whp is about 100whp over stock man. quite a big jump. but good luck and let us know how it goes.
